Be it known that 1, John ,ll. Burs, ii (iii 1 zen of the United States,.rei-ziding at Lerninie, in the county ol Albany end hitiite ol'Wyoming, have invented new and. useful iui provemnts in Apparatus forRecovering Tin and Solder, oil which the following is: a specification.

ll has been shown as provided with u hinged Jl his invention relates toan improved a; 5 .1

paratus and procese for recovering tin and solder from scraps of Middle,old cans made of tin-pla1te, and like uniterizi-l which. is .lrequentlypermittei'l to go to waste, the olijerl of the invention heinn' torecover and to sure i the tin and solder, which is (soinperntivilyvaluohle. I

A further oh j eutol the invention is to provide an apparatus of simpleand improved constrilotion,v whereby the procebeoi rover-- erin; the tinand solder n'my be rarried into operation. elliciently anderonoxnivully.

.l would have it understood that in place of :1 fll'l'llLl-(IO such ashas been conventionally shown in the drawings burners fortheconsuniplion of gas or vapor may be utilized u'ithinthe scope ol theinvention. In any ease; however, it is desirable that the upper ends ofthe lurnziee-wiills be inclined win the dirvvtion of each other, aswillbe clearly seen in Fig. .5 of the drawings, a ciiiiipz'iizitivelyruirrow nlit or opening 11. being left between i the upper edges of saidl'urnn-eeni'zills.

Alongthe furnace-walls adjacent to the outer sides of the hitter there:r're placed inolde 12 for the reception of the tin and solder \i'l'ichis reeovered. by the use of the improved apparatus.

When the drum heemnes sullicieutly lzented to fuse he tin and solderupon the liupln.te cr'n ('onlniuml therein, rotary motion. at n eonsidernlilo speed is imparted to the Hindi rnrryin; suio drum, thuscausing the molieu tin and solder to be expelled by centrifuge oestrikethe hood or shield and the uptpir walls 9, whereby it and em ty onessubstituted in place thereof..

After t e valuable metals have been recovered from the contents of thedrum'the scra is removed from the latter, after which it may berecharged for a repetition of the oper- [5 foraminous'drum or containerwhichis supported for rotationin such'a manner as to be capable ofbeingrapidly rotated (so. as to cause the valuable meta s, which have beenreduced to a molten condition, to be expelled by centrifugal actionthrough the perforations of said drum or container.

It is obvious that the old tin cans which constitute the material mostfrequently operated upon will become unsoldered, and the pieces of whichthey are composed will be agitated and shaken by the rotation of thedrum so that the molten tin or solder will be rapidly and thoroughlyexpelled. Hence b the. present invention the valuable metas ma berecovered and saved speedily with li-tt. e manual labor and at a totalexpense which is nnichbelow. the value of the metals recovered by theoperation.

The improved apparatus may be constructed and installed for operation ata small expense, and it may be successfully operated without havingrecourse to skilled labor.

What is claimed is' I 1. An apparatus for recovering tin and solder fromold tin-plate, including a foraminous'container'supported for rotation,means beneath the container for heating the latter and, its contents,side Walls beneath the con-v tainer having their upper portions inclinedin the direction of each other, molds disposed alongside of the sidewalls, and a hood arranged over the drum and the molds and. fittingsnugly against the latter.

2. In an apparatus of the class described, a foraminous. drum supportedfor rotation, a furnace arranged beneath the drum andhaving side wallsthe upper portions ofwhich are inclined in the direction of each other,receiving-molds disposed along the side walls and in contact therewith,and a hood or shield constituting a covering for the drum, the furnaceand the molds, and fitting snugly against the latter.

In' testimony whereof affix my signature in presence of two witnesses.
